Hypocephalus armatus

It is found in Brazil and is popular in museums and collections for its curiosity value and adaptations to digging in soil that make them appear outwardly similar to the mole crickets.

This rare species has an evident sexual dimorphism, as the very strong legs of the males are more developed than in females.

In both sexes the flight wings are absent, the prothorax is ovoid and shiny black, the dark brown elytra are fused together and the hind legs are much heavier than the others and adapted for digging.

Adult males can be found from November to March, usually after the rains, when they dig into the soil.
